Rina Hidaka has two announced TV anime roles in 2026: she voices Caroline Ramsey in the October 2026 series Weakest MAX Lady and Koyō in The Eccentric Doctor of the Moon Flower Kingdom, which has no premiere date set.
Rina Hidaka has two upcoming lead roles in TV anime adaptations announced within a week of each other in late May 2026. On May 22, Kadokawa announced that Hidaka would voice Koyō, the young doctor protagonist of The Eccentric Doctor of the Moon Flower Kingdom, a Chinese-style imperial medical fantasy adapted from Tōru Himuka's manga. The series is directed by Koichiro Kuroda at Studio Elle, with scripts by Risa Mizuno and music by Shiho Terada. No premiere date has been set.
Eight days later, on May 30, the first promotional video for Weakest MAX Lady revealed Hidaka as Caroline Ramsey, the otome game heroine in a villainess-type love comedy. The series is directed by Nobuaki Nakanishi at Jumondo and is scheduled for October 2026. Hidaka is joined by Sora Amamiya and Haruki Ishiya in the cast.
Both roles place Hidaka as the central female lead in adaptations of long-running manga properties, though the two series differ significantly in tone and setting. The Eccentric Doctor of the Moon Flower Kingdom is a shojo medical fantasy with 15 manga volumes as of May 2026, while Weakest MAX Lady is a love comedy with a reincarnation premise. Neither story provides information about Hidaka's other current or upcoming projects beyond these two roles.
